Water Security: Rivière des Anguilles Dam project to meet domestic and irrigation needs in the South

The Rivière des Anguilles Dam project stands as one of Government’s most important and largest infrastructure undertakings, representing an investment of several billions of rupees to mobilise additional water resources and meet current and future needs up to 2050.

The statement was made, this morning, by the Minister of Energy and Public Utilities, Mr Patrick Gervais Assirvaden, during a visit to the site of the upcoming dam. He was accompanied by the Junior Minister of Foreign Affairs, Regional Integration and International Trade, Mr Hambyrajen Narsinghen; the Member of Parliament, Mr Roshan Jhummun; and other personalities. Designed to supply water for both domestic and irrigation purposes, the Rivière des Anguilles Dam will serve the South, South-West and part of the South-East of Mauritius, benefiting approximately 50,000 households.

Construction of the dam is expected to begin in November 2026 and to be completed by November 2029. The dam will be built as a bituminous faced rockfill dam, measuring 2,200 metres in length with a maximum height of approximately 60 metres. It will have a storage capacity of 12.5 million cubic metres and a regulated annual yield of 47 million cubic metres.

In a statement, Minister Assirvaden recalled that water resource management remains one of Government’s top priorities, particularly in the face of rising demand during the dry season and increased pressure caused by episodes of heavy rainfall and flooding. In this context, he emphasised that the Rivière des Anguilles Dam project is being fast-tracked, with the support of three funding agencies, to ensure its timely implementation and to strengthen long-term water security in the southern region.

Mr Assirvaden further underlined that the project will bring significant relief to the relevant areas by providing a reliable and sustainable supply of water for both domestic use and agricultural activities. “Once the dam becomes operational, water resources currently allocated to the region will be redirected to other areas facing shortages, thereby enhancing overall water distribution and management across the country,” he added.
